SUSTAINABILITY
Sustainable principals are intrinsic to our design solutions.
BJA employ sound Environmental Sustainability Design principles augmented by ESD innovations. These include: optimised building & glazing orientation, thermal mass, low embodied energy material specification, shading, ecological water + waste water management, alternative energy systems, passive heating & cooling systems like night flushing, improved insulation & ventilation systems and landscaping strategies for cooling and water retention/re-use, in addition to current mandatory energy + water saving & thermal comfort performance requirements.

BJA designed ten homes within Narara eco-village on NSW Central Coast achieving House Energy performance ratings between 6.1 and 7.6 stars and designed the ‘off grid’ Barrington Eco House
We work with specialist ESD consultants to advise and design systems, which has resulted in innovations such night flushing systems, the use of heat pumps with hydronic systems to reticulate hot water in slabs, improving overall thermal performance and costs.


The Barrington Eco House is self-sufficient using ‘off the shelf’ systems and good design practice. PV cells generate power, rainwater is collected and stored for re-use, sewage is treated on site. Solar panels are backed up by a fuel stove for in-slab reticulated water for space heating, and the micro climate is moderated using water cascades. This is all within the context of a healthy bio-dynamic farm!
We promote the use of non-toxic paints, particularly in our school projects, and ensure natural light and cross-ventilation plus optimal solar access and appropriate thermal mass.


The increasing incidence of allergies has seen a growth in the availability and usage of non-toxic paints and building boards. Healthy environments provide optimum learning and living.
ESD has an ethical dimension in reducing the impact of our footprint on the planet and creating intergenerational equity, to which BJA are committed.
